Depiction of man in gate (9)
I believe the answer is:
portrayal
'depiction' is the definition.
(I know that portrayal is a type of depiction)
'man in gate' is the wordplay.
'man' becomes 'Ray' (Man Ray was a o0th-century artist).
'in' is an insertion indicator.
'gate' becomes 'portal' (I've seen this in another clue).
'ray' put into 'portal' is 'PORTRAYAL'.
'of' is the link.
(Other definitions for portrayal that I've seen before include "Artistic depiction" , "drawing" , "Picture or description of royal prat" , "Study" , "Depicting characters" .)
